The purpose of this study
was to prepare a checklist of the woody plants growing on the campuses of St.
John's University and the College of St. Benedict. The main goal of the
project was to document the campus trees and shrubs to provide a baseline data
set. In addition, we hope it is useful to anyone who is generally
interested in our campus plants.

interested in our campus flora.

Methods:

This study was conducted by
examining specimens in the CSB/SJU Bailey Herbarium (CSB). We recorded the
name of the species, it's herbarium accession number and the campus on which the
specimen was collected. In most cases it was obvious where the specimen
was from. However, in several cases specimens were listed from
"Collegeville." These were assumed to be collected on the St. John's
campus.

There are several species
that we knew to grow on campus (e.g., Acer ginnala, Betula nigra) but for which
which we had no herbarium records. These species, which were positively
identified in the field are identified as "PO" (personal observation). In
addition, we learned about a number of cultivated species from Fr. Paul
Schwietz, the late St. John's Arboretum director. These are listed in Table 1 as
"Paul Schwietz - PO."

Although the primary focus
of this list is on native and naturalized plants that grow without cultivation,
several landscape species are included. No attempt was made to include all cultivated species
growing on campus.

We recorded more than 150
(157) species of woody plants in approximately 34 different families (Table
1). The campus flora is particularly well-represented by the maple
(Aceraceae), birch (Betulaceae), honeysuckle (Caprifoliaceae), oak (Fagaceae),
pine (Pinaceae), rose (Rosaceae), and willow (Salicaceae) families.
